This invention-relates to a ski harness, and particularly to such adevice in which straps or other binders for holding the ski tothe shoeare eliminated. rIhis not only avoids 'V5 the necessity of fastening andadjusting r`'I0 from the ski is taken.

The difficulties accompanying the attach- Ving of the usual ski to theshoe of the skier, accompanied by the dangers resulting from the sameloosening or breaking, have been serious objections to the popularity ofvthe vsport of skiing. j

My invention is so designed-'and arranged thatthe ski can be fastenedtothe shoe by simply shoving the shoe into the spring clamp whichcooperates with plates carried by the shoe to produce a close union ofthe shoe and "ski.

In the accompanying drawings I have illustrated, and in thespecification described a form of my improved ski harness which hasproven highly efficient and durable-in use.

Throughout the specification and drawings similar reference numeralshave been used to indicate the corresponding parts.

In the drawings:

Fig. 1 is a view of a shoel in position on a ski. v 4

Fig. 2 is a view of the shoe equipped with my shoe plate.

i 35 Fig. 3 is Va plan view Vof the top ofa ski before the shoe isinserted withinthe harness. Fig. 4 is a similar View after the shoe hasbeen inserted. Y

Fig. 5 shows a modified means of connecting the shoe and shoe plates. vl

I have indicated at 1 a portion of thejski, and at 2 a shoe. My skiharness consists of a vpair of spring clamping members indicated at 3and 4. Each clamping member is riveted at its rear end as at 5 to thevertically disposed ange 6 of an attaching plate 7 which is permanentlyfastened as at 8 `9-1O to the' upperrface Vof the ski.

The clamping membersl areV fastened to each other at their free ends asby the hook the ski.f

and hole connection indicated at 11. This is an adjustable connection,there being several holes 11 formed in one of the clamping members inanyof which the hook 11 of the A opposite clamping member may beselectively entered. f

Each clamping member carries an inwardly disposed locking pin or stud12, the free end of which is beveled as at 1 3. The vertical flanges 6of the'y attaching lplates 7 are provided each with a clearance hole l14aligned with said locking studs.

Screwed or otherwise attached at either side ofthe shoeis a shoe plate15. Each shoe plate 15 has a vertically ldisposed lateral flange 16, andeach flange is provided with a locking hole 17 adapted to be alignedwiththe locking holes 14 in the ski plates and with the llocking studs'12carried by .the clamps 3. and 4. The forward corners of these flanges16, abovethe holes 17, are beveled as indicated at 18.'

In' use the attaching`plates7 'are first fastened to the ski. This mayinvolve some adjustment of the' plates to insure that their flanges 6are correctlyV spaced and yfor this purpose the'attaching plates 7 areeach laterally lslotted as indicated at 20 to receive adjustment blocksV21. In applying the attaching plate 7 to the ski therefor, the properadjustmentis first determined and the blocks 21 screweddown to the skiby means vof the screws 8, after which the screws 9 and 10 are screwedin to assist in holding the plates in the proper relation. i

When the shoe with its attached shoe plates 15 is inserted into thespace between the vertical flanges 6 of the ski plates, the beveledspring clamping members 3 and 4 urges said studs into said holesthus'locking the shoe to `As a modification, the shoe plates may ,belprovided with the inserts 23 and 24 Yshown lin.` Fig. 5 of the drawings.These inserts 23 and 24 are'simple headed fastenings in the nature ofhollow screws which are incorporated in the shoe during its process ofYous modifications in the design of the ski plates and shoe plates andthe manner of latching one to the other may also be resorted to withoutdeparting from the spirit of my invention if within the limits of theappended claims. Y

Vhat I therefore claim and desire to secure by Letters Patent is l. In aski harness, a pair of adjustable plates adapted to be secured to a ski,said plates having upwardly extending lateral anges, a pair of shoeplates adapted to be attached to a shoe sole and having upturned lateralflanges .adapted to lie inside of and against said ski plates, said skiplates and said shoe plates having registering apertures, an adjustableclamp carried by said ski plates, studs carried by said clamp andadapted to enter said registering apertures in said ski and shoe platesso as to lock said ski and shoe to each other. s

2. In a ski harness, a pair of adjustable plates adapted to vbe securedto a ski, said plates having upwardly extending lateral flanges, a pairof shoe plates adapted to be attached to a shoe sole and having upturnedlateral flanges adapted to lie inside of and against said ski plates,said ski platesA and said shoe plates having registering apertures, anda pair of spring arms carried by said ski `plates and adjustablyengageable with each yother at their forward ends, studs carried by saidspring arms and adapted to enter said registering apertures in said skiand shoe plates so `as to lock said ski and shoe to each Y other.

and a pair of adjustable spring arms carried by .said ski plates, studshaving beveled vfree endscarried by said springarms, said beveled .endsof said shoe plates engaging the beveled free ends of said studs so asto guide the same into said apertures to lock said ski and shoe to eachother.

4. In a ski harness, a pair of adjustable plates adapted to be securedto a ski, each plate comprising a slotted member and an adjustment blocktherein whereby the plates may be attached to the vski in properposition to receive the shoe of the wearer, said plates having upwardlyextending lateral fianges, a pair of shoe plates adapted to be attachedto a shoe sole and having upturned :lateral flanges adapted to engagesaid ski plates, and means locking said shoe plates t0 said ski plates.

5. In a ski harness, a pair of adjustable plates .adapted to be securedto a ski each comprising a slotted member and an adjustment blocktherein whereby the plates may be attached tothe ski in proper positiont0 receive the shoe of the wearer, said plates `having upwardlyextending lateral flanges, a pair of shoe plates adapted to be attachedto a shoe sole and having vupturned lateral flanges adapted to lieinside of and against said ski plates, said ski plates and said shoeplates having registering apertures, a spring clamp carried by said skiplates, studs carried by said clamp and adapted to enter saidregistering apertures in said ski and shoe plates so as to lock said skiand shoe to each other.

6. Means for detachably interlocking a shoe to a tread structure, suchas a ski vor Vthe like, comprising opposed .pairs ofrelatively Arigidand relatively yieldable locking formations on the shoe and treadstructure, respectively, interengageable with each other upon .endwisesliding `movement of the shoe and its locking formations into the zoneof action of Vthe locking formations carried by the ski or other treadstructure yielding to permit the entrance therebetween of the lockingformations carried by the shoe and thereafter returning to positiontointerlock with said shoe formations.
